Date found(s): 26 August, 2026
Location(s) found: Logger’s Lake, Shannon County, MO
Notes: The WGNSS group came upon the individual pictured here in Shannon County in August of 2026. When it realized we discovered it, we were in for a short but thrilling experience. The caterpillar arched its long anal prolegs over its back, extruded the yellow and red portions thereby doubling their length, and then thrashed them about wildly in an obvious attempt to threaten and dissuade us. Unfortunately, this act lasted merely seconds, and it could not be coaxed into a repeat performance after we had set it up for photographs. If this method of dissuasion does not do the trick, the caterpillar can spray acid from a gland in its thorax.
